For skydivers and BASE jumpers, tracking is a crucial step towards wingsuit flying. Whether you plan to move up to a wingsuit, or just hone your tracking skills, the SUMO is the answer.

Our mission for this tracking suit was to find the ideal balance between volume and stability, with an emphasis on solid internal pressure and quick inflation. The SUMO has performance that is comparable to one-piece tracking suits, with the comfort and ease of use that is inherent in a simpler 2-piece system.

The No-Wobble system secures the pants to your knee area, helping to prevent excess movement in the pants while tracking. This unique feature gives a compact and precise feel in the track, and is very simple to use. It is also optional - the pants can be flown with or without the Velcro fastened.

The overall suit volume is balanced, with a slight taper from waist to ankle for ease of handling. The SUMO provides quick starts and excellent forward speed, with simple and intuitive control.

The SUMO is built to the same high standard that has made our wingsuits the benchmark for quality in our sport. We look forward to hearing what you think of this exciting new tool, and hope that you enjoy flying it as much as we have enjoyed developing it.

Please remember that as with all BASE jumping equipment, it is extremely important to skydive the SUMO extensively before attempting to use it for BASE jumping.

Force Feed

The majority of power in a tracking suit comes from the pants, and the SUMO benefits from an array of mylar-fed inlets which rapidly inflate and maintain pressure inside the suit.

Quick Starts


The SUMO's oversized arm inlets provide immediate control after exit. Upper arm inlets allow early inflow after exit, and the shoulder inlets maintain pressure in flight, through all angles of attack.



Inside the pants at the knee, we have added a Velcro enclosure which anchors the pants to your leg, reducing pant-leg wobble and increasing control and performance. This is one of the most crucial features of the SUMO, giving the pants a more precise and solid feel when maneuvering in high speed tracks.



The high collar, cinched wrist, and extra-long torso help to reduce leakage and maintain pressure in the jacket.



Four zipped chest pockets provide plenty of phone / emergency electronics / gear storage, and the jacket is lined with airmesh and lycra/fleece for comfort and structure.



The knees are heavily reinforced with Cordura, with 5mm of closed cell foam padding for protection and structure.

Toe Tension


To maximize fit performance, three toe-tension settings are available, using a lightweight and simple buckle/strap adjustment.



Highly durable and custom colored 10C YKK zips run up both legs.
